c. E. FU-NK TRACK LINING GAUGE Filed Sept. 28, 1957 wadei/zm/zm ATTOR N EYS Patented Jan. 3, 1939 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to improvements in track lining gauges and has for its primary object the provision of a. device for lining tracks and determining the degree of curvature thereof and which may be readily secured thereon.

Another object of my invention is to provide a device of the above described character equipped with means for securing the same on rails of different sizes.

Other objects and advantages will be apparent from the following description, appended claims and annexed drawing.

Referring to the drawing wherein like refer ence characters designate like parts throughout the several views:

Fig. 1 is a top plan view of a portion of a track rail illustrating the application of my invention thereto.

Fig. 2 is a side elevation of one of the rail members.

Fig. 3 is a top plan view thereof.

Fig. 4 is a side elevation of the intermediate rail member.

Fig. 5 is a top plan view of the intermediate rail member on an enlarged scale.

In practicing my invention, I employ a plurality of rail members 5, 6 and I constituting the ioremans jack and guide block members, respectively, adapted to be secured to the traction section of a rail of ordinary construction. The rail members 5 and I are adapted to be secured to a curved section of a rail a predetermined distance apart, the intermediate rail member 6 being secured to the rail between the members 5 and l and located centrally therebetween.

The rail members are formed of elongated sections 8 and 9, each section terminating in a depending rail engaging flange Ill. The sections 9 are each formed with an elongated slot II for receiving therethrough a bolt I2 secured to the adjacent section 8.

The sections 9 of the members 5 and I are provided with a vertically extending rod I3 constituting a sight element adjacent their respective sections, the vertical axis of said rod aligning with the inner face of the respective depending fianges II'I.

Mounted on the section I I of the. member 6 is a transversely adjustable gauge I4 formed with an elongated slot I5 for receiving therethrough the bolt I2. Mounted on the end of said gauge, adjacent the flange II] of the section II, is a vertically extending rod I6 secured thereon by means of suitable nuts H.

The gauge I4 is provided on the upper face thereof with a reading or scale indicia I8, the same being of a linear graduation comprising inches and fractions thereof. Wing nuts I9 coacting with the bolts I2 serve to secure the sections of the members 5 and I together and also secure the sections and gauge I4 of the member 5 together in adjusted position relative to each other. When the gauge I4 is adjusted relative to the sections 8 and 9, the scale I8 will denote the distance in inches and/or fractions thereof the i sight element I6 extends laterally of the track. Such reading will indicate the degree of curvature of the rail when the sight element I6 is aligned with the sight elements I3, each inch of the scale denoting a degree of curvature.

In use, when it is desired to line a curve, the foremans and guide block members are arranged at remote points on a rail and the jack block member is secured at an intermediate point thereon, for instance, the foremans and guide members spaced a distance of 62 it. apart and the jack member interposed therebetween 31 ft. from each of the aforesaid members. The degree of curvature of the track is calculated by the number of inches of the lining gauge carried by the jack member projecting laterally beyond the line of sight between the foremans member and the guide member, the line of sight bisecting the vertical extending sight elements carried by the respective members.

The sight element carried by the guide member is of a greater length to permit easy alignment when sighting.

While I have shown and described my invention in connection with rail sections of tracks, it is to be distinctly understood that the same is adaptable for use in connection with engaging curves in roads, buildings and the like and that various changes and modifications may be resorted to without departing from the spirit of the invention or scope of the appended claims.

Having described my invention, what I claim 1. A device of the character described, comprising, a ternary of rail members adapted to be secured on a rail in predetermined spaced relation, each of said members formed with a pair of horizontally disposed sections having depending rail engaging flanges, one section of each member formed with an elongated slot, a bolt carried by the other section of each member and extending through said slot and equipped with a nut adjustable for clamping the respective sections of each member together and to the rail to permit adjustment of said sections to accommodate rails of various sizes, a sight element fashioned on one section of each of two of said members, an adjustable gauge overlying a section of the other member and formed with a slot slidably accommodating the bolt of said member whereby to effect adjustment of said gauge relative to said sections, said gauge provided With a sight element coacting with said gauge in a manner whereby said gauge will indicate the degree of curvature of l a rail when said last mentioned sight element is aligned with the first mentioned sight elements.

2. In a rail lining device, a rail member comprising a pair of relatively adjustable horizontally disposed sections adapted to overlie the head of a rail, each section terminating at one end in a depending rail engaging flange for engaging the sides of said head, one of said sections formed with a longitudinally extending slot, a bolt secured to the other of said sections and extending upwardly through said slot whereby to permit relative sliding adjustment of said sections, a. horizontally disposed gauge contactually and slidably overlying said slotted section and formed with a similar slot for accommodating said bolt whereby to permit sliding adjustment of said gauge relative to said sections, a perpendicular sight element mounted on said gauge and coacting therewith in aligning a rail, and a member carried by said bolt for maintaining said sections and said gauge in adjusted position on said head.
